PATENT OFFICE HAROLD T. LOVELL, OF NEW CASTLE, ENNSYLVNIA AUTOMOBILE VENTILATOR Application filed January 28, 1929.

The invention relates to improvements in ventilators adapted to rest upon partially lowered window glasses of automobiles and to engage the usual glassguiding grooves.

It is the principal object of the invention to provide a new and improved ventilator which is well adapted for use with automobile Windows of various widths. In carrying out this end. a horizontally elongated, sheet metal plate which is apertured for Ventilating purposes, is manufactured of the maximum length ever required and hence is adapted to be cut off to any shorter length which may be needed. One end of this plate is intended to engage one of the glass-guiding grooves and a spring-projected shoe is employed for engaging the other groove, and it is a further aim of the invention to provide novel means for connecting this shoe with the plate regardless of the length to which the latter be cut.

With the foregoing in view, the invention resides in the novel sub]l ect matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a side elevation of the invention and a sectional view of a portion of an automobile window, showing the former in position with respect to the latter.

Fig. 2 is a horizontal sectional view on line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 1 but illustrating the outer side of the ventilator, whereas Fig. 1 discloses the inner side thereof.

Fig. 4 is a horizontal sectional view on line 4-4 of Fig. 1.

Fig. 5 is a vertical transverse sectional view as indicated by line 5 5 of Fig. 1.

Fig. 6 is an enlarged side elevation of one end of the device showing the spring-projected shoe and the means for connecting it with the plate.

Fig. 7 is a horizontal sectional view on the correspondingly numbered line of Fig. 6.

Fig. 8 is a transverse sectional view on line 8 8 of Fig. 6.

In the drawings above briefly described, the numeral 9 denotes a horizontally elongated sheet metal plate of the maximum length ever Serial No. 335,607.

needed, said plate being apertured for ventilating purposes. In the present showing, this plate is provided with two screened ventilating openings 10 and with other openings 11 whose effective size may be regulated by v55 pivoted. spring-held dampers 12. Cowls or the like 14 are secured to the plate 9 by tongues or other desired means 15, and they enten d at the outer side of the plate so that the openings 10-11 open into them. The front 160 ends of these cowls are closed and their rear ends open. so that upon travel of the machine. suction will be created to draw out the foul air, sufficient fresh air entering around windows and doors. through floor boards, etc.

The upper edge of plate 9 is provided with an inwardly projecting inclined flange 16 for reception in the usual top groove 17 for receiving the window glass 18 when the latter is completely raised. One end 19 of this plate 70 is adapted for reception in one of the usual side guide grooves 2O of the window frame and a spring-proiected vshoe 21 is provided at the other end of said plate for reception in the other si d e guide groove 20a. The plate 9 may "75 he cutl off' to anv required length and novel provision is made for connecting the shoe 21 with the end 19a of said plate regardless of the len oth to which the latter be cut.

A carrying plate Q7 is provided for the shoe 80 21. said plate lying against the inner side of the plate 9 and being provided with a hook 28 to engage the plate end 19tl as shown for instance in Figs. 1, 6 and 7. regardless of the length to which said plate be cut. The shoe 21 is preferably in the form of a plate slidablv connected with the plate 27. The upper au d lower edges of plate 27 are provided with laterally bent reinforcing flanges 31-32. the flange 31 being inclined transversely and in contact with the lower side of the flange 16 V while the flange 32 abuts a flange 33 projecting inwardly from the lower portion of the plate 9 to overlie the upper end of the par- 95 tially lowered window glass 19. Plate 21 is flanged at 3122-32?L to engage flanges 31-32. A spring 29 acts against vertical flanges Sil- 8in on the plates 21-27 to project the former, and projection is limited by a bolt 301 passing through said spring and through said flange.

By preference, the lower edge of plate 9 is bent upwardly upon itself as at 34, is then bent laterally at and this lateral portion is bent upon itself as denoted at 36, the formations 35 and 36 `eonstituting the flange 33 above `described and imparting `:to it a rigid two-ply construction. In the angle between the flange 33 and the subjaeent part ot the plate 9, a pad 37 of felt or the 'like is glued or otherwise fastened to engage `the window glass 18.

In applying the device, the glass 13 is partly lowered, the plate 9 is eut to the proper lengthnnless the twindow be oit maximum width, andthe plate 127 is then engaged with .one end of said plate19 by sliding said end `loe tween the plate?? and the hook 28. 'This hawingbeen done,the tlange30 may loe-used as a handle toiy inwardly :move the shoe 2125MB eiently-to ,permit eng gementof the plate '9 with the` glassreeeiving groove 20. `Illhen rthe plateis properly positioned and @ange 30 released, the shoe 21- enga-ges `the :groove 20a' and yhas ,aeontinual ytendency to ,move ontwardly due to `the spring 29, whereby the ventilator `is yheld irmly in` Iposition `even though the 18be lowered to` `quite an yeX- tent. Wlien this glass is raised, it seats snugly against `the pad 370i teltaor other :suitable rmateraal .and rattling ,otparts is `prevented. Ordinarily, the'openings 11 4may remain closed but it more ventilation is desired, may be opened to the required extent.

i On `account ot the existing' advantages `for ,tliedetails herein disclosed, they are pret- Aeralily followed However, within the scope .ot the invention as claimed, variations `may ,be made.

,Ielaim i 1. In an automobile ventilatoradapted for insertion over a lowered window glass, a

horizontally `elongated apertured sheet metal `plateof the maximum length ever required,

`whereby.said `plate is adapted to be out oth to any shorter length needed, one end of said plate being adapted `for reception in one of theaisual glass-guiding grooves-of an automobile window, a spring-.projected shoe for reception in the other glassfguiding groove, and means for connecting said shoe with said plate regardless 0f the length ,t0 which the latter be out.
